In the form of this at 4 months old
I love you Cliffy Mutt.
I know I don't get 13 more years, but I'll take what you can give me and I promise not to make you suffer.
You are the best dog ever and in many ways the best being to have come into my life in the past 13 years. You are definitely the one constant.
I don't know what I'll do without you.
